Don't waste time striving for perfection in things that don't matter; for these things accept the advice of experts you trust and/or take what's good enough.

I don't believe that society, or individuals, automatically self-correct. I think acts of will are required. And I have tried to suggest several things that you should will for yourself and for others, and work to achieve. I wish each of you a life in which good enough is good enough - a life governed by reasonable expectations, and filled with love and with work that is a calling. A life as part of a community that listens to you just as you listen to it.
